George Risk Industries 400-B Surface Mount Contact Brown

Product Description

The George Risk Industries 400-B is a surface mount industrial contact designed for door and window security sensing applications. This unit features a concealed terminal design that keeps wiring hidden from view, supporting clean, professional installations. The 400-B is sold as a single unit and is suited for use in commercial and residential security, access control, and alarm systems. Licensed security and low-voltage electricians typically specify this type of contact for perimeter protection circuits where a discrete, surface-mounted form factor is required.

The 400-B is appropriate for surface mounting on doors, windows, and frames in both residential and light commercial settings. Its industrial-grade construction makes it a practical choice for security integrators and alarm technicians working on new installations or replacements. The concealed terminal configuration reduces the risk of tampering and simplifies the finished appearance of the installation.

Secure the contact body to the mounting surface using appropriate hardware, and route wiring through or behind the concealed terminal before final connection.
